A special thanks to http://www.mrbalihai.com who said: thanks to the astute bOINGbOING ( http://www.boingboing.net )readers who pointed out that the bizarre sculptures featured in the video were part of the Ruta de la Amistad public sculpture project at the 1968 Olympics in Mexico City, and that this clip came from Raquel's eponymous 1970 television special.
